1. General Information
The UNI (MP100) is a single sensor, portable, personal toxic gas monitor. It displays gas
concentration continuously on a big segment LCD. It also monitors the STEL, TWA, Peak and
Minimum (for O2 only) values, and these can be displayed on demand. High, Low, STEL and
TWA alarm thresholds are configurable. The shell is made of high strength, durable material. The
two-key operation is simple to use. Sensor and battery can be replaced easily. Calibration is also
very convenient.

4. Operation
4.1 Turning the Unit On and Off
Press and hold the Right Key for 3 seconds, until the red light, buzzer, and vibrator all trigger,
followed by the green light, and the LCD displays “On”. To turn off, press and hold the Right
Key from normal display mode for a 5-second count-down, until the unit displays “Off”.

4.2 Warm-up Sequence
After powering on, the unit enters a warm up and self-test sequence, shows the firmware version

as follows:

   •   If the sensor cannot be identified or is not installed, the screen alternately displays

       and         .

   •   If the Bump or Cal Due setting is enabled and the due date has passed, the display will

       alternate between            or          and          . The Left Key must be pressed to
       acknowledge, otherwise the instrument will turn itself off automatically after 15s.
Lastly, the following values will be shown accordingly:
   • High alarm threshold
   • Low alarm threshold
   • STEL (short-term exposure limit) alarm threshold
   • TWA (8-hour time-weighted average) alarm threshold
4.3 Normal User Mode
4.3.1 Real Time Readings
When warm-up is complete, the unit enters normal mode and starts displaying
instantaneous gas concentrations.

By pressing the Right Key the user can check other values including STEL,TWA, PEAK, MIN
(for O2 only) and Alarm Log. The display returns to real time readings from any other screen if
there is no key action for 60 seconds.
4.3.2 STEL
This displays the Short Term Exposure Limit (STEL) calculation, which is the
average concentration in a moving window over the previous 15 minutes. The

                                                5
UNI MP100 User's Guide - Single-Gas Detectors - mPower Electronics Inc.
UNI MP100 User’s Guide

STEL value rises and falls with some lag time over the instantaneous reading.
A STEL alarm cannot be cleared except by turning the unit off and back on,
but will clear automatically after 15 minutes in clean air.
4.3.3 TWA
This displays the Time-Weighted Average (TWA) calculation, which is the
average concentration times the fraction of 8 hours that the instrument has
been on. The TWA value is similar to a dose in that it rises but never falls,
until it is reset by turning the unit off. Likewise, a TWA alarm cannot be
cleared except by turning the unit off and back on.
4.3.4 Peak
The Peak screen shows the highest value since the unit was
turned on.

Press the Left Key to enter the Clear Peak screen and Press
the Left Key again to acknowledge and clear the Peak value.

4.3.5 Minimum (Oxygen Sensor Only)
The Minimum screen is used for the oxygen sensor only
and shows the lowest value since the unit was turned on.

Press the Left Key to enter the Clear Min screen and Press
the Left Key again to acknowledge and clear the Min value.
4.3.6 Alarm Log
Up to 50 alarm events lasting ≥5 seconds are logged into
memory and the last 10 such events can be viewed on the
instrument. When A 1 is reached using the Right Key, it
flashes between the A 1 screen and a screen showing the
alarm concentration and type. Values preceded by a “--” with no alarm label indicate a negative
concentration alarm event. Use the Left Key to cycle through the 10 available alarms. To view all
50 alarm events along with date and time stamps, it is necessary to use a Docking Box or
CaliCase connected to a computer with mPower Suite software.
4.3.7 Backlighting
Holding down the Left Key for a few seconds causes the red alarm LEDs to stay on for 5
seconds. This helps the user read the display when in darkness.

4.4 Configuration Mode
In Config mode, the user can change parameters and calibrate the unit. In general, use the Left
Key to increase the number or confirm an operation, and use the Right Key to move the cursor or
go to the next menu item.
4.4.1 Entering and Exiting Config Mode
Press and hold the Left Key and the Right Key together for 3 seconds until the password screen

is displayed,       followed by        , with one digit or cursor flashing, to prompt the user to
enter the password. The default password is 0000. Use the Left Key to increase the number, and
the Right Key to move the cursor, and the Left “OK” Key again to accept the password input and
enter Config mode. If the digit input is incorrect, use the Right Key to move the cursor and Left
Key to change the input.
NOTE: The MP100 default password is 0000.

To exit Config Mode, press the Right Key until          is displayed, and acknowledge with the
Left Key to return to Normal Mode. Alternatively, just wait for one minute and the unit will
automatically revert to Normal Mode.

4.5 Sensor Calibration and Bump Test
Before the unit can monitor gas correctly, it needs to be calibrated using zero and span gas.
Calibration and Bump Tests are recorded in the instrument datalog for compliance purposes.
4.5.1 Zero (Fresh Air) Calibration
Zero calibration sets the baseline for the sensor. It is preferably done in fresh air at the same
ambient temperature and humidity as will be used for measurements. However, nitrogen, dry
cylinder air, or other gas source known to be free of detectable compounds can also be used. One
exception is that for an oxygen (O2) sensor the Fresh Air Calibration sets the value to 20.9%, so
air must be used.

From the         menu, press the Left Key to start a zero calibration. The unit displays a 15-

second count-down followed by the calibration result as either         or        . The user can

abort the zero calibration during the count-down by pressing the Right Key, after which
is displayed.

UNI MP100 User's Guide - Single-Gas Detectors - mPower Electronics Inc.
UNI MP100 User’s Guide

4.5.2 Span Calibration
Span calibration determines the sensitivity of the sensor to the gas. Recommended calibration
gases and concentrations are listed in Section 7.6 at the end of this manual and in TA Note 4
(available at www.mpowerinc.com). Special calibration procedures for highly reactive gases are
described in TA Note 6. Oxygen sensor calibration is reversed from other sensors and uses pure
nitrogen with 0% oxygen during the span procedure and 20.9% oxygen (air) during the fresh air
“zero” procedure. We recommend using a fixed flow regulator of at least 0.3 LPM but no more
than 0.6 LPM. Use as short tubing connections as possible.
Span Calibration Procedure
1. Connect the Calibration Adapter to the span gas cylinder’s regulator and snap it into place
   over the UNI sensor.

2. Enter the         menu, start the gas flow, and press the Left Key to start the calibration
   count-down. The calibration time is typically 60 seconds but may be shorter or longer
   depending on the sensor type.

3. To abort the span calibration during count-down, press the Right Key and       is displayed.

4. After count-down, the span calibration result       or        is displayed.
5. Turn off the gas supply and remove the Calibration Adapter.

                                           CAUTION
  During normal monitoring, never operate the MP100 with the Calibration Adaptor attached
  because it will block diffusion of gas into the sensor.

4.5.3 Bump Test
A Bump Test is a quick check to ensure that the sensor and alarms are working properly. It is

done with the same gas as is used for span calibration. Enter the          menu, start the gas flow,
then press the Left Key to start bump count-down (typically 45 seconds, but varies with sensor).

After count-down, the bump test result          or         is displayed.

To abort the bump test during count-down, press the Right Key and             is displayed.

Although a Bump Test is a recorded event in the datalog, the user can always do an unrecorded
bump check such as by breathing into an oxygen monitor just to verify that the sensor and alarms
are functioning.

4.6 Setting Instrument Configurations
4.6.1 Alarm Limits
 MP100 toxic gas monitors alarm with 2 beeps & flashes per second when concentrations are
over the Low Alarm setpoint, and 3 beeps & flashes per second when over the High Alarm
setpoint. See Section 7.5 for a summary of alarm signals and Section 4.6.2 for Oxygen Monitor
alarms.
All the preset alarm limits, HIGH, LOW, STEL & TWA can be changed. From these menus

                 ,                 ,                 , and              , press the Left Key to
change the corresponding alarm limit, using the same process as for entering a password (Section
4.4.1):
The current setting value is displayed, with the first digit flashing:

Use the Left Key to increase the current digit, cycling from 0 to 9:

Use the Right Key to move the cursor to the next digit:

After all digits are entered, use the Right Key to move to the “OK” symbol,
and press the Left Key to save the entry. The unit will display SAVE for a
few seconds while storing the value; it is not necessary to press OK to
initiate saving.

                                               9
UNI MP100 User’s Guide

Silence Mode can be entered using mPower Suite (Section 5). In this mode, the audio alarm is
disabled when exceeding the Low Alarm, with no change to the visual and vibration alarms. The
audio alarm is still enabled when exceeding High, STEL, TWA or Overrange Alarm conditions.
NOTE 1: The MP100 will show an error message “Err” if:
 • The Low alarm is attempted to be set higher than the high alarm setting.
 • The High alarm is attempted to be set lower than the low alarm setting.
 • The entered value is outside the measuring range.
4.6.2 Oxygen Monitors
Standard Oxygen Monitors: Oxygen monitor alarms function differently than toxic gas
montior alarms in that the normal ambient air reading is 20.9% and an alarm is triggered when
the reading goes BELOW the Low alarm setpoint or ABOVE the High Alarm setpoint. Oxygen
monitors do not have STEL or TWA alarms.
Inert Oxygen Monitors: Oxygen monitors programmed for inert gas applications do not alarm
when the O2 concentrations are below the Low Alarm setpoint or above 19.5%. They give a Low
Alarm (2 beeps/sec) when between the Low and High Alarm setpoints and a High Alarm (3
beeps/sec) when between the High Alarm setpoint and 19.5%. The default Low and High alarm
setpoints are 4% and 5%, respectively, but can be adjusted, while the 19.5% limit is fixed. Thus,
this version is useful both for oxygen deficiency monitoring in normal ambient air when users do
not wear a breathing apparatus, and in inert gas environments, where breathing apparati are
required, to warn of high oxygen levels that may allow explosion to occur.
4.6.3 Span Value
The span gas concentration can be changed from the Cal SET menu using
the same process as for setting alarm limits.

NOTE: The MP100 will show an error message “Err” if:
 • The Span setting is less than 5% of the measuring range or greater than the measuring range.
 • For the Oxygen sensor, the span setting is greater than 19.0%.
4.6.4 Bump/Cal Intervals

In the Bump and Cal Interval menus, the LCD alternates between:            and        , or

and        . Press the Left Key to enter the menu and change the interval using the same process
as for setting alarm limits. Note that a value of 0 means Bump or Cal notifications are turned off.
NOTE: The MP100 will show “Err” if the interval is out of the valid range: 0-180 day(s).

4.6.5 Gas Concentration Unit
The gas concentration unit menu alternates between         and    . Press the Left Key to enter the
gas unit sub-menu, showing the currently selected unit blinking. Unit options include x10-6, ppm,
mg/m3 and µmol/mol for toxic gas sensors, and % for oxygen. Use the Right Key to scroll
through the unit list and select, and the Left Key to confirm and exit.

                                               10
UNI MP100 User’s Guide

4.6.6 Vibrator Enable/Disable
The vibrator consumes a lot of power and can be disabled to extend the battery life. The Vibrator

menu alternates between              and          . Press the Left Key to change the vibrator

enable/disable status. The current vibrator status is displayed, alternating between                 and

       if enabled, or between            and          , if disabled. Use the Right Key to change the
status, and use the Left Key to confirm and exit.

4.6.7 Power-on Zero Enable/Disable
The sensor baseline may shift due to changes in environment conditions, such as temperature or
humidity, and require a zero calibration. The MP100 can prompt the user to zero calibrate every
time the unit is powered on, and this feature can be enabled/disabled.

The Power-on Zero menu alternates between                 and         . Press the Left Key to change
the power-on zero enable/disable status. The current status is displayed, alternating between

       and         if enabled, or between              and        if disabled. Use the Right Key to
change the status, and the Left Key to confirm and exit. When the unit is re-started and user is

prompted with            to zero, it must be initiated within 30 s or else the zeroing is skipped.

4.6.8 Fast Power-on Enable/Disable
If fast startup is enabled, the screens showing HIGH/LOW/STEL/TWA alarm threshold values
will be skipped during warm up sequence. On start-up, the unit shows the firmware version
number and then goes directly to concentration readings.

The fast power-on menu alternates between               and         . Press the Left Key to change the
fast startup enable/disable status. Enable or disable Fast Power-on and confirm the status using
the same process as for Vibration Alarm or Power-on Zero enable/disable.

4.6.9 Configuration Reset
If some unit parameters are incorrect and the user has difficulty correcting them, this menu can
be used to set the all the configuration parameters back to the factory default condition. From the

alternating        and          display, press the Left Key to enter the           (reset) menu. Then
press the Left Key to confirm or the Right Key to abort the reset.

7. Maintenance and Specifications
                                        CAUTION!
Maintenance should be performed only by a qualified person who has proper training and fully
understands the contents of the manual.

7.1 Battery Replacement
The battery typically lasts 3 years, but may be drained faster if the unit has
frequently gone into alarm. When the charge is low, the unit displays a red
battery icon and a battery low alarm is triggered once per minute. When the

battery is dead,              is displayed and the battery dead alarm triggers
every second. The battery needs to be replaced, as follows:

1) Turn off the MP100 and place it face down on a soft surface.
2) Use a T10 Torx screwdriver to loosen each of the four screws by turning them
  counterclockwise.
3) Remove the top cover after carefully unplugging the buzzer connector.
4) Slide the battery out of its compartment.
5) Place the new battery into the compartment with its “+” end oriented toward the “+” on the
  printed circuit board.
6) Plug in the buzzer connector and reinstall the top cover.
7) Re-install the screws through the back cover. Be careful to not overtighten the screws.

                                                                                 Filter

  (3.6V, 2700mAH, taille AA) ou celle de EVE Énergie Cie., Lté, pièce No. ER14505.

7.2 Sensor Filter Replacement
A “peel-and-stick” filter should be used on the MP100 in order to keep debris from fouling the
sensor. Replace the filter whenever it appears dirty, is clogged with particles, has contacted liquid,
or when sensor response becomes weak and/or slow. Use external clip-on filters when operating
in dusty environments for easier filter exchange.

1) Turn off the MP100 and remove the top cover as described above for
   battery replacement.
2) Peel off the old filter, and gently press a new filter onto the sensor.
3) Reconnect the buzzer and reinstall the top cover as described above for
   battery replacement. Be careful to not overtighten the screws.

7.3 Sensor Replacement                                                              External Filter Clip

MP100 models are designed for easy sensor replacement. CO and H2S sensors have typical
operating lives of 5 years, while others are 1 to 2 years, as per warranty (See Specifications in
Section 7.8).
1) Turn off the MP100 and remove the top cover as described above for battery replacement.
2) Replace the old sensor with a new one. Make sure the pins are not bent or corroded. Align the
   pins to the corresponding holes and push the sensor straight in. The sensor should fit flush
   against the printed circuit board.
3) Check the instrument filter and, if needed, replace as described in the previous section.
4) Reconnect the buzzer and reinstall the top cover as described above for battery replacement.
   Be careful to not overtighten the screws.
                                          CAUTION!
Sensors are not interchangeable. Use only mPower sensors, and use only the sensor type
specified for your MP100 monitor. Use of non-mPower components will void the warranty and
can compromise the safe performance of this product.

* The default span setting equals the recommended span gas concentration.
** Calibration of these sensors requires a gas generator or other special precautions. See TA Note 6 for
   recommended procedures and gas sources.
† Suggested calibration interval. Actual required interval must be defined by user and may be shorter under harsh
   conditions or longer under favorable conditions – see TA Note 3 for details.

* Oxygen sensors in MP100 use pure nitrogen or other inert gas for both Span and Bump Test.
† Standard O2 alarms are triggered when O2 levels go either below the Low Alarm or above the High alarm. Inert
  monitor alarms are off below the Low alarm or above 19.5% and on above Low & High alarms but below 19.5%.
